Improvement in erasers



UNITED STATES A. H. HOOK AND H. B. ADAMS, OF NEW YORK, N. Y.

IMPROVEMENT IN ERASERS.

Specification forming part of Letters Patent No. 56,415, dated July 17, 1866.

To all whom it may concern:

Be it known that we, A. H. HOOK and H. B. ADAMS, of the city, county, and State of New York, have invented certain new and useful Improvements in Erasers and like articles, by which the manufacture thereof is cheapened and improved; and we do hereby declare and ascertain said improvements, referring to the accompanying drawing, in which the several forms we have devised are shown as follows:

Heretofore erasers have been forged out of steel or iron into the form desired at great eX- pense and polished, asis usual with edge-tools, and fitted into handles, which greatly enhanced their cost, so that they could notbe afforded to the public at a price which enabled them to be generally introduced.

By our improvement we are enabled to furnish an eraser superior to those before in use in some particulars at less than a quarter of the present prices, while they are equal to said erasers for all practical purposes.

For this purpose we take a thin plate of steel similar to the article used in the manufacture of steel pens, and strike out and swage into proper form with suitable and well-understood swages and dies in a manner well known to manufacturers of steel pens, and we form the shanks of said erasers like those of steel pens, either of tubular form, as at A, or segmental, as at B in the drawing.

The blade may be either flat, triangular, or curved in its cross-section. We prefer the crimped or dishing form as making the article stiffer and more easily sharpened, although that is not imperative, as the simple curve will answer.

It is obvious that the shank of our eraser may be formed into a pen, and thus, by reversingit or the handle, writin g or erasing may be done.

Having thus fully described our new manufacture of erasers, what we claim, and desire to secure by Letters Patent, is-

Forming erasers substantially as and for the purposes herein described.
